Fringe partly trimmed, gently (4)
I believe the answer is:
edge
'fringe' is the definition.
(synonyms)
'partly trimmed gently' is the wordplay.
'partly' indicates a hidden word (part of the clue is used).
'EDGE' is hidden in the letters of 'trimmed gently'.
(Other definitions for edge that I've seen before include "Creep" , "Snick - boundary" , "The part farthest from the middle" , "Rim,border" , "Inch; border" .)
